The word crazy because I'm mentally disabled. It's defined as someone who is mentally deranged, specifically a violent individual, but it's used to describe anyone with a mental illness or disability, no matter how simple or complex. When I was in high school, my brother had a friend who asked me why I was sad all the time and I reminded them that I had depression, and my brother corrected me by saying, "No, you're just freaking crazy." The word implies that being mentally ill or disabled makes one a bad person, somehow. It stigmatizes them.
